    Ok there's the thing:
    I had a 2G iPhone and lost it. I didn't want to change my plan so I looked for iPhones on eBay and such. I found one, activated it, got a new SIM card for it, but I ended up not liking the iPhone and returned it. I kept the SIM card though. I was wondering if I could use the SIM card I already have (from the 2G) and put it into a new 3G iPhone without having to change my contract. I'm planing on turning off the 3G network as I'm not really interested in using it if I can keep my old contract.

    Is you SIM still active? If Yes, then you can put your current active AT&T SIM into a iPhone 3G and use the your existing original iPhone data plan.

    How do you plan to get the iPhone 3G without a contract and a data plan?

    You will also receive SMS Txt messages from AT&T about your use of an invalid iPhone data plan. They will know you have the 3G based on the IMEI of the iPhone 3G as soon as it connects to the network.
